Research

Physics-informed GAN framework

We enhance the conventional physics-informed neural network framework by implementing the principles of data-driven computational mechanics into GANs.

Research

FE-FFT-based modeling

We present a two-scale finite element (FE) and fast Fourier transformation (FFT)-based method incorporating finite strains and a thermo-mechanically coupled constitutive model for elasto-viscoplastic polycrystalline materials.

New course director for CompEng

2025-01-21

The international Master's program in Computational Engineering has been offered at the faculty since 2000 – with great and ever-increasing success and interest from prospective students from all over the world. Recently, there has been a change in the course director. On the occasion of his retirement, long-time course director Prof. Dr. rer. nat. Klaus Hackl, former chair of the 'Chair of Mechanics - Materials Theory,' handed over the course directorship to his successor, Prof. Dr.-Ing. Johanna Waimann. We are delighted to welcome her as the new "CompEng Head"!
